    • The key symptoms of Parkinson's disease (PD) are caused by degeneration of dopamine neurons originating in substantia nigra. Whereas, transcription factor LMX1A is crucial for the differentiation of mesencephalic dopamine neurons, LMX1B appears to be important for both the development and the survival of these cells. The aim of this study was to investigate if genetic variation in LMX1A and LMX1B differs between patients with PD (n = 357) and control subjects (n = 1428) by genotyping 33 single nucleotide polymorphisms (SNPs) in LMX1A and 11 SNPs in LMX1B. Three SNPs in LMX1A and one in LMX1B were associated with PD. After splitting for gender, six SNPs were associated with PD in women and four in men. The significances obtained did not survive correction for multiple testing, and our results should hence be interpreted with caution, but are partly in line with a previous report, and should thus be of sufficient interest to encourage further studies of these genes in PD.

  • Cyclooxygenase-2 polymorphisms in Parkinson's disease.

    • Accumulating evidence indicate that cyclooxygenase-2 (COX-2) is of pathophysiological importance for the neurodegeneration in Parkinson's disease (PD). For example, in a large epidemiological study, use of NSAIDs was associated with a lower risk of PD. Genetic variants of the COX-2 gene might therefore influence the risk of developing the disease. The genotype distribution of four common single nucleotide polymorphisms (SNPs) in the COX-2 gene (rs689466:A496G, rs20417:G926C, rs5277:G3050C, rs5275:C8473T) was analyzed in PD patients and control subjects in a Swedish population. No differences could be seen between the PD-patient and controls regarding the A496G, G926C, and G3050C SNPs, but the allele frequency of the C8473T SNP was found to differ when male patients were compared to controls (P = 0.007). In females no difference could be seen between PD-patients and controls. In conclusion, the results suggest a possible influence of the COX-2 C8473T SNP in PD, although it only seems to be of importance in men.

  • Interaction of polymorphisms in the genes encoding interleukin-6 and estrogen receptor beta on the susceptibility to Parkinson's disease.
  • 2005

    • The multifunctional cytokine interleukin-6 (IL-6) is involved in inflammatory processes in the central nervous system and increased levels of IL-6 have been found in patients with Parkinson's disease (PD). It is known that estrogen inhibits the production of IL-6, via action on estrogen receptors, thereby pointing to an important influence of estrogen on IL-6. In a previous study, we reported an association between a G/A single nucleotide polymorphism (SNP) at position 1730 in the gene coding for estrogen receptor beta (ERbeta) and age of onset of PD. To investigate the influence of a G/C SNP at position 174 in the promoter of the IL-6 gene, and the possible interaction of this SNP and the ERbeta G-1730A SNP on the risk for PD, the G-174C SNP was genotyped, by pyrosequencing, in 258 patients with PD and 308 controls. A significantly elevated frequency of the GG genotype of the IL-6 SNP was found in the patient group and this was most obvious among patients with an early age of onset (

  • Investigation of genes coding for inflammatory components in Parkinson's disease.

    • Several findings obtained recently indicate that inflammation may contribute to the pathogenesis in Parkinson's disease (PD). Genetic variants of genes coding for components involved in immune reactions in the brain might therefore influence the risk of developing PD or the age of disease onset. Five single nucleotide polymorphisms (SNPs) in the genes coding for interferon-gamma (IFN-gamma; T874A in intron 1), interferon-gamma receptor 2 (IFN-gamma R2; Gln64Arg), interleukin-10 (IL-10; G1082A in the promoter region), platelet-activating factor acetylhydrolase (PAF-AH; Val379Ala), and intercellular adhesion molecule 1 (ICAM-1; Lys469Glu) were genotyped, using pyrosequencing, in 265 patients with PD and 308 controls. None of the investigated SNPs was found to be associated with PD; however, the G1082A polymorphism in the IL-10 gene promoter was found to be related to the age of disease onset. Linear regression showed a significantly earlier onset with more A-alleles (P = 0.0095; after Bonferroni correction, P = 0.048), resulting in a 5-year delayed age of onset of the disease for individuals having two G-alleles compared with individuals having two A-alleles. The results indicate that the IL-10 G1082A SNP could possibly be related to the age of onset of PD.
